The last caller was removed in 2014 in commit fb5a515704d7 ("powerpc:
Remove platforms/wsp and associated pieces").
Once generic_secondary_thread_init() is removed there are no longer
any uses of book3e_secondary_thread_init() or
generic_secondary_common_init so remove them too.

Commit 702f09805222 ("powerpc/64s/exception: Remove lite interrupt

registers by default, and explicitly restore them in paths where it is
required.
But it missed that the facility unavailable exception can sometimes

fsl_asrc_dma_hw_params() invokes dma_request_channel() or
fsl_asrc_get_dma_channel(), which returns a reference of the specified
dma_chan object to "pair->dma_chan[dir]" with increased refcnt.
The reference counting issue happens in one exception handling path of
fsl_asrc_dma_hw_params(). When con
